The wife and I are looking at buying a house/land on a lake in Tennessee somewhere. Currently the leading lake is Watts Bar because we like the proximity to Chattanooga and the mountains. We are trying to find the best lake in the area for sailing a trailer tri (Corsair 760 most likely) and the Hobies obviously.

What are people’s thoughts about the area? Can I sail year round?

We are planning a trip to Tennessee for thanksgiving break (drop kids off with the grands in Pigeon Forge).

I'll take a stab at this. I grew up in East TN on Cherokee Lake. One thing you need to know about E. TN lakes is the majority (I can't think of one that isn't) are TVA lakes. This means that most will be pulled down in the winter for flood control. When I was young that meant they started to go down in August and by October the cove behind my parents house was dry. I think they delay it now but by Nov the lakes are really low. You can sail in the winter early spring but have to be careful of stumps etc (assuming you have enough ramp to float the boat off the trailer). Hobies are fine but the Corsair might not be.
